INKIG MECHANISM Specification of Letters latent.

Patented Feb. 6, '1917.

To all whom t may concern:

Be it known that I, RonEn'r Hon, a citizen of the United States, residing at Battle Creelnin the county of Calhoun and State of Michigan, have inventednew and useful Im rovements in Inking Mechanisms, of which the following is a specification.

This invention relates to inking mechanism for printing presses.

One object of the invention is to provide a mechanism that may supply ink separately for each column-of the printing and in which the feed may be independently adjusted for each column so as to secure the desired printing of all portions of the sheet or web.

Another object is to provide a mechanism that will eliminate the feeding of ink through fine apertures or slits which may become clogged by the thickening of the ink or the presence of impurities or coarse particles in the ink; and still other objects will appear in the following description and the apended claims.

f eferring to the drawings: Figureul is a sectional end elevation of the improved inking mechanism; Fig. 2 is a sectional' plan view of part of the mechanism; Fig. 3 is a side elevation lwith parts broken away to show construction; Fig. 4 is a sectional plan view f a detail; Fig. 5 is a sectional end elevation of adjustingrmechanism; Fig. 6 is anr end elevation, partly in section,`of a modification; Fig. 7 is a sectional plan view of part of the mechanism shown in Fig. 6; Fig. 8 is a sectional 'side elevation; Figa 9 is a developed plan view of the ad]us tmg means; Fig. 10 'is an end elevation in Seetion showing the ink' container end assoiated parts; Fig'. 11 is a diagrammatic view showing operation of adjusting mechanism;

and Figs. 12, 13 and .14 are end sections in elevation of various forms of ink containers.

In' some forn'isof1 printing presses it is desirable thatltlie inking mechanism be adapted 'to *supply ink separately for each I column of the/ printing and that the mechanism be further equipped with adjusting means so that the supply of ink for each column may be regulatedindependently'of the ink supply for the ntlierfcolumnsl, Up

to the present time, inkin'gmechan'Sm-that Y @has secured'these resultslias'included means v fordelivering the ink in-'the'form of a thm film; o r'in sheets,- or in the form or condit'iont'cf spray.v4 In all such constructions' the ink is fed substantially in a continuous stream. f

The improved mechanism herein disclosed secures the advantages outlined above and also Provides for feeding the ink mechanically' and intermittently. One advantage 'of this intermittent feed is that the presence of impurities or coarse particles in the ink, oi'

the thickening of the inl: itself, will not y cause the feeding to become imperfect or deective 1n any column or columns. It isobvious that, given a certain 'desiredrate of feeding, if the ink be supplied intermittently the amount delivered at any one time must be greater than when it is supplied continuously. It is further obvious, as. a consequence of this, that any passages through which the ink is to be fed Will'be considerably larger in cross-sectional'area in thel case of intermittent feed than in the case of continuous feed, and that they will be less easy to choke4 up or become inoperative.- The saine consequence also follows in other forms of feeding mechanism where the ink is transferred by roller contacts and the like. Other advantages are that the intermittent feeding of the ink is more positive and certain.;

the quality of the ink becomesof less importanceiso far as the feeding operation is concerned; the independent supply to each column may be more closely regulated, and the supply of ink for each column is moire assure Figs. 1 to 5 inclusive show a preferred Vform of construction that will accomplish all of'these'objects. Upon the framel of thepress is mounted an ink containerll,` roughly cylindrical in form and supplied with ink through a pipe 12. The container terminates in cylindrical headsl, 13 which form bearings for a shell 14 surrounding the container. I rotate about the common axis of the con?V tainer and shell and is driven by rollersl, E

15 in contact therewith. As best shown Vin Fig. 3, the shell includes a series ofV feeding The shell 14 is adapted tof devices comprising 1n the pre'sent-illustra-l t tion of the invention .staggered apertures .1G-,4169, each so-called aperture composedof i a group of small holes, leach group representing a separate column. I :nk maybe fed through each of these apertures 16 if the shellv14' be rotated. As show nin Fig.` 1, any' aperture 316 is'- in communication with `the ink container only' when the aperture" is in the lowerniost position it occupies during the rotation of the shell. At this point ink is fed through the aperture to the dis- `a series of sectors. 13.15 mortised together .as ind' lated at 1S)1 1S) to form liquid tight joints. Each sector is the width of a column of theI matter to be printed and is in registration with one of the series of apertures 16. lach sector slides between the .adjacent sectors, and each is adapted to be moved in a circular path having the same axis as the shell 14A. rl`he sectors are.provided with respective shoes or scra'pers 2o. having a lower face 21 in contact with the shell H and a second face .22 curved to conform with the periphery of a rollerf'll which extends longitudinally along the/lx'ittom of the ink container 11. lVhcn 'any sector is positioned so that theface 2'. is in contact with the roller 23, communication with the ink container is cut ott' and the related aperture 1G will have its supply of ink cut ott'. The. amount of ink supplied -for any column aperture will var v with the space between the face Q2 a'nd.1'oller 23.

As best Shown in l*`igs. 1. 2 and 5. each sector is provided with a gear segment which meshes with a pinion :iti carried upon -a shaft 27. llach shaft 2T terminates at the,

Side of the machine in a bolthead 28 adapted to be engaged by a wrench. The `adjustment of any one of these holtlieads will rotatethe respective shaft 27, pinion 26. seg` ment and sector 1S and thus determine the amountof ink to be supplied, to the particular column related to thev bolthead. As indicated in the drawings., the geausegments are staggered with relatioi ""to each other so as to permit the circular arrangementof the adjusting shafts 27 shown.-

Figs. to 11 inclusive, illustrate a modified forni of mechanism securing the same results. As shown in Fig. 10. this form includes :n inl: container 30 attached lto the frame 31 of the press land surrounded by a rotary shell 32 having its bearingsl 33 upon. the ends 34 of the container.

'lhe shell is rotated by rolls 35,35. The ink container has an aperture opening 31' along the bottom` through which the ink passes into contact withv the inner surface of the shell at` its lowest point. A scraper 3T is wos-'ided to ite-ep the shell free of excess ink. 'The shell is provided with a series of passages 9,8 which are couidistant radially with respect lo each other. as shown in Fig. 1U.` but which are .staggered in longitudinal relation with each other as shown in Fig. H. Lthe lateral positions as shown correslmnding with the columnsl of matter to be printed in the inanner described with reference to the apertures lo. in the former embodiment of the invention. this construction provides for an intermittent feeding of ink through the passages Ilo. the feeding taking place when the aperture is at its lowest point.

The adjusting means to regulate the' quantity of mk supplied to each column in-.

cludes a valve fl for each of the passages its, "l`hc valve is l'ormedin the end of a stem or shaft 40 carried in the shell and the, outer end ofthe shaft is provided with a camming head +1. best shown in Figs. o and l1. A. pair of enacting cams t2 and 42" are positioned in the path of each camining head ll, the lugs 43. -t-t of which are adapted-to contact with the cams so that the position of the cams determines the angular movement of the head 41 and shaft 4t), as indicated in Fig. l1` this movement operating toaadjust the valve 2h), s shown in Fig. Si. each of the canuning heads 4l projects from the end of the shell a different extent than the others. so that cach pair of cams contacts with and controls the angular movement ofbut one camming head.

rl`he. cams 42 and 42" are mounted upon shafts l5 and lo respectivel)Y and are rotated. in unison from a thumb piece 4T mounted in the frame and joined to a pinion -LS which meshes with pinions 19, 50 attached respectively to shafts 45 and 46. To prevent disturbance of idjustment, the -thinnb piece -tT may be further. equipped with a stai wheel 31. as lshown in Fig. (l, operating with a spring detent 52 to hohl the cams in their adjusted position.

Figs. 12, 13 and lt illustrate modifications of the' ink container showing various forms of ieservoirs and arrangements for delivering the ink to the rotary shell.

(,hanges and variationsl may be-niade in the constructions by which the invention is carried into ettect. plicant is broadly the application of intermittent feed or mechanically operated devices in the feeding of ink in separate columns and the control or regulation of the ink supplied to each column as desired. and many various devices maybe employed Lto carry out this invention. The invention is not therefore to be confined to the particular constructions herein shown and described.
